HAIR IRON.

Application led August 1, 1921. Serial'No. 488,953.

T o all whom it may concern:

Be it known that I, JOSEPH PING CANE- AvRI, a citizen of the UnitedStates, and a resident of Port Arthur, in the county of Jefferson andState of Texas, have invented certain new and useful Improvements inI-Iair Irons, of which the following is a specification.

The present -invention relates to hair irons, and has for its object toprovide a device of this character which has a wide range of utilityTbeing capable of advantageous use in either crimping or straighteningthe hair in any desired manner and to any desired degree and which is ofsimple and durable construction, reliable and safe in operation and easyand inexpensive to manufacture.

Other objects and advantages of the invention reside in certain novelfeatures of construction, combination and arrangement of parts whichwill be hereinafter more fully described and particularly pointed out inthe appended claims. reference being had to the accompanying l drawingsforming part of this specific-ation, and in which:

Figure 1 is a side elevational view of the preferred embodiment of theinvention;

Figure 2 is a top plan view;

Figures 3, 4 and 5 are group views in elevation, illustrating varioustypes of dies utiized in conjunction with the invention; an

Figure 6 is a view, partly in section and partly in plan, illustratingthe structure common to all the dies.

Referring to the drawings wherein for the sake of illustration is shownthe preferred embodiment of the invention, the numeral 10 designatesgenerally a pair of crossed handles which include shanks 11 pivotallyconnected to each other, as at 12 and hand grips 13 carried by theShanks, each shank having a grip integrally formed therewith at one end,One of the grips carries an eye 14 whereby the iron may be suspendedwhen not in use. The Shanks are offset and attened at the ends thereofremote from the grips to provide seats 15 for the dies generally at 1G(see Figures 2 and 6).

The dies are preferably constructed of metal and are provided in pairsor sets, each set being adapted t0 perform a certain peculiar operationdependent upon the particular characteristics of the die. As shown inthe draw ings all the dies are preferably in the form of a block, a faceof which abuts one of the seats 15 and fastening means such as setscrews 18 are carried by the seats and have threaded engagement with theblocks of the dies to secure the dies in position on the seats.

Each set of dies may differ from the others in various ways such as insize, shape, heat conducting or other physical properties of the metalcomposing the same but the most important and salient feature ofdifference resides in' the construction and formation of the coactingworking heads or faces of the dies and in all of the sets these coactingworking faces are mating or complementa-ry.

In the set of dies shown in Figure 1 the working faces or heads comprisea series of curved ribs or corrugations 20 extending transversely ofeach die, the series on one die interfitting with the series on theother die when the dies are brought together as shown in the drawing. Itis obvious that the size and number of the ribs or corrugations maly bevaried. y

n F1gure'3 the intertting ribs are designated at 21 and are preferablyrectangular m cross section, as shown.

In Figure 4.- the working face or head of one of the dies is concaved asshown at 22 and the other is convexed as shown at 23.

In Figure 5 the working heads or faces l are plane as designated at 25.

Electric heating means is provided for each die and for this purposeeach die is provided with a cavity 27 extending from one side face ofthe block composing the die to adjacent the other. A helix or coil ofwire or ribbon orA other resistance ele- Inent 28 is arranged in thecavity. The resistanceelement is enclosed by a casing 29 of insulatingmaterial and its convolutions are insulated from each other in anydesired manner as by mounting on a plate of mica or the like. A plug 30is threaded in the outer end of the cavity 27 and confines the heatingelement 28 therein. This plug may be of insulating material, ifpreferred. Flexible conductors 31 supply the heating element withcurrent and extend through nickel tubes 32 carried by the slianks 11 andfrom the tubes into the cavity 27 wherein they are connected to theterminals of the heating element.

In use, the operator grasps the grips 13 and applies the dies to thehair with the requisite degree of pressure. The electric heating elementheats fthe dies most efficiently for the purpose of shaping and xing thehair so that the hair may be subjected to the action of heat andpressure. The degree of pressure is variable at will and the instrumentmay be utilized to twist, turn or otherwise manipulate the iron.Moreover the hair may be subjected to the character of bending, flexionor other action appropriate in the circumstances Since the dies With therequired formation of Working face may be readily attached, the Setscrew facilitating change thereof and the threaded plug 80 affording aready access to the heating element for connecting and disconnecting theconductors.

I claim:

l. A hair iron comprising a pair of crossed handles ,including Shankspivotally connected, grips carried by said Shanks, said Shanks havingtheir ends opposite said grips offset and flattened to provide seats,dies comprising metallic blocks having faces abutting said Seats, setscrews carried by the seats and having threaded engagement With-theblocks, said blocks having cavities therein, a helix arranged in saidcavity, an

insulating casing for said helix, a plug closing Said cavity, conductorsleading to said helix and tubes carried by the Shanks and accommodatingthe conductors.

2. A hair iron comprising a pair of crossed handles including Shankspivotally connected, grips carried by said Shanks, said Shanks havingtheir ends opposite said grips offset and flattened to provide seats,dies comprising blocks having faces abutting said seats, means forreleasably securing said blocks to said seats, said blocks havingcavities therein, and electric heating means for said blocks includinghea-ting elements arranged in said cavities.

3. A hair iron comprising va pair of crossed handles including Shankspivotally connected, grips carried by said Shanks, Said Shanks havingtheir ends opposite said grips formed to constitute seats, dies arrangedon said seats and having complementary Working faces, means forreleasablysecuring Said dies to said seats, and electric heating meansfor said dies.
